The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 15 GRIMSTHORPE AVENUE sales from June 2018 and August 2020 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the June 2018 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the August 2020 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.
15 GRIMSTHORPE AVENUE might now be worth an estimated £282,252.

The 24.9% inflationary increase is applied to the most recent sale price for 15 GRIMSTHORPE AVENUE of £226,000 on 14th August 2020. For the value to have increased from £226,000 to £282,252 over the five years and six months to February 2025, the following assumptions must hold true:
